Domain-specific¶
- Fitts's Law
- This shape, and its derivation from Shannon channel-capacity theory treating the movement as a transmission of spatial information across a noisy motor channel, supply the predictive law together with the interpretive frame usually invoked to motivate it — a chosen lens rather than an established mechanism, as T4 sets out
This sourceMacKenzie works out the information-theoretic derivation behind Fitts's law and shows that Fitts's own log2(2A/W) form follows Goldman's large-signal approximation rather than Shannon's Theorem 17, proposing the Shannon form log2(A/W + 1) instead; the note grounds the channel reading but does not endorse the 2D/W shape as the one Shannon's theorem gives.
